Hertel 66693698 Jobber Length Drill Bit Set 115 Pc Hss

Product Description

The HERTEL 66693698 is a 115-piece jobber length drill bit set engineered for metalworking and general-purpose drilling applications. Built from high-speed steel (HSS) with an oxide finish, each bit features a 135-degree split point that reduces walking on contact and allows drilling to start without a center punch in most setups. The set covers wire gauge sizes #60 through #1, letter sizes A through Z, and fractional sizes from 1/16 inch up to 1/2 inch in 1/64-inch step increments. The full range in a single case makes this set a practical bench staple for shops and service trucks handling daily mixed-material drilling work.

This set is rated for heavy-duty metalworking and is suited for use in machine shops, maintenance facilities, and fabrication environments. The 135-degree split point geometry is particularly effective on harder metals where bit walking and heat buildup are common concerns. It covers a broad size range that supports drilling pilot holes, clearance holes, and production runs across a wide variety of fastener and hardware specifications. The included metal or plastic storage case keeps bits organized and protects cutting edges between uses.

Key Features

• 115 pieces covering wire gauge #60 to #1, letter A to Z, and fractional 1/16 inch to 1/2 inch
• 135-degree split point reduces bit walking and eliminates the need for center punching on most surfaces
• High-speed steel construction for durability in metalworking and multipurpose drilling
• Oxide coating finish for basic corrosion resistance and surface hardness
• 1/64-inch fractional step increments for close-tolerance hole sizing
• Includes metal or plastic storage case for organized storage and transport

Compatibility

Designed as a general-purpose jobber length drill bit set for use in standard three-jaw drill chucks and compatible with common benchtop drill presses, hand drills, and mill setups used in metalworking and multipurpose applications.

Installation Notes

Installation and bit changes should be performed with the drill or machine powered down and unplugged or locked out per applicable safety procedures. Secure bits fully in the chuck and verify seating before operation. Cutting speed and feed rate should be matched to bit diameter and workpiece material to avoid premature wear or breakage. A licensed machinist or qualified maintenance technician should perform setup in production environments where applicable.
